That’s when Harlem High School students in the Vet Doc class showed their work to their documentary subjects — World War II and Korean War veterans — their classmates, families and friends for the third annual Harlem Vet Project gala and presentation.

“You taught us what it is to be young at war,” senior Zhané Suppeland said, introducing a short documentary, “Young at War,” that combined footage from interviews of five military or civilian participants in the war effort and archival war footage.

Suppeland’s biggest lesson learned from hours of “Greatest Generation” interviews and documenting those stories? “You can’t give up, even when you want to.”

This year’s class produced 42 15- to 30-minute documentaries; DVD copies were presented to the interviewees at the end of the gala. The edited documentaries also will be submitted to the Illinois Veterans & Community Classroom Project; raw footage will go to the Library of Congress to be archived as part of the Veterans History Project.
